You must run skypes and at least one FS instance on one EC2 instance, depending on the performance, you could run 1 FS + (1 upto 64 or perhaps 128) skype instances on 1 EC2. But note that if one skype instance crashes it may cause the entire FS/skype unstable(although there are tricks and solutions), so, instead of 1FS+128skypes per EC2, you might want, say, (1FS+24Skype) * 5EC2. As giovanni said, you should try with real world test to find out the best combination. On Sat, Sep 11, 2010 at 12:27 AM, Shamun toha md <shamun.toha@gmail.com> wrote:
Today i talked with Amazon EC2, they have 8 Core Cpu (can grow even more then that), 68 GB RAM( can grow more), Bandwidth ( can do anything) so there is no issue which still saying no you can not do this because of that. The answer is still yes even with correct hardware tune.
We can pay what we will use for (that's another issue as a technical point of view). But for Skype, which one should i take?
if i want to run 20 or 100 skype duplicate accounts for Amazon EC2, do i need 100 skype instance + FreeSwitch instance = 101 total instance with Amazon EC2? How do we use the mod_skypopen in terms of instances for cloud servers, is that counted as 1 instance?

I would highly doubt of your reasoning. You have to make real actual tests, and not base predictions on simple arithmetics. But this is just my opinion.

Hello,
Thanks, we can always consult with more experts from FS, that is must. But just consulting here for one assumption before opening a final ticket.
Can we not just use CentOS 5.5. And then take a hardware like following:
1. CPU 6 core or 8 core or 12 core: -
http://accessories.us.dell.com/sna/products/Processors/productdetail.aspx?c=...
2. Mother board: To have 12 x 4 times = 48 Core -
http://www.supermicro.com/products/motherboard/Xeon7000/7500/X8QB6.cfm?SAS=Y
3. 2 core each with reserved 4GB RAM
2 core can handle 20 channels of skype instance. So, 48 Core / 2 = 24 x 20 = 480 Skype channels possible. With power of hardware and proper calculation on this, bandwidth is not a problem, there are many backbone providers.
Am i right? Still its possible in theory? Please fix me if i am wrong,
Thanks & Best regards

Shamun,
from you mail seems that there are some details of mod_skypopen that you've not got.
First of all I would counseil you to read *entirely* mod_skypopen wiki page, you will spare yourself lot of time and frustrations: http://wiki.freeswitch.org/wiki/Mod_skypopen_Skype_Endpoint_and_Trunk
All the mod_skypopen knowledge available to humankind is in that page.
T1 has 24 channels, so not much difference from 20 channels http://en.wikipedia.org/wiki/T-carrier
mod_skypiax can work only on Linux or Windows, because it needs Skype clients running on the same machine where FS is running, and there are no Skype clients for *BSD or Solaris.
After reading all of the wiki page, you should do your tests, because performances are very much dependant from the machine-kernel-os you use. Skypopen is most tested and developed on CentOS and Ubuntu.
Also, if you plan an Enterprise deployment (I mean, many channels with reliable operation), you must be prepared to invest a sizeable amount of time to deeply understand all of the variables involved. Or you can contact consulting@freeswitch.org for professional help.
Skype uses it's own codecs, it's not L16 on the net. L16 is between FS and Skype client.

Hi,
Lets say 1 wants, Enterprise production plan with mod_skypopen, not a target of 20 channels only. lets assume more channels (T1) sort of target:
# Question operating system should be CentOS or FreeBSD or OpenSolaris?, to win a little more CPU space for this Skype processor monster.
Then what server hardware platform should it be, to provide support physically too:
1. What is the CPU should be target to handle more skype channels? ex: 8 CPU in 1 hardware ( 20 skype instance x 8 = 160 channels? ), which server or os support this even?
2. What is the RAM should be? ex: 20GB? which hardware or os?
3. What server it should be? Cloud or Private co-located?
4. What is the bandwidth plan? ex: 10GB or 2MB?
5. L16 codec, will it be using inbound also for outbound? What will be the Kilo bytes per seconds?
There is no reference what CPU with What unit of Ghz used? ex: http://wiki.freeswitch.org/wiki/Skypiax
Thanks for your feedback
